RAILWAY-CAIR- noon.

To all whom it may concern Be it known that we, WALTER L. CoNwELLandALLEN E. OSTRANDER, residing at Montclair, Essex county, New Jersey,and Edge- Wood, Bergen county, New Jersey, respectively, and beingcitizens of the United States, have invented certain new and usefulImprovements in Railway-Car Doors, of which the following is a full,clear, and exact description, such as will enable others skilled in theart to which it appertains to make and to use the same, reference beinghad to the accompanying drawings, which illustrate the preferred form ofthe invention, though it is to be understoodthat the invention is notlimited to the exact details of construction shown and described, as itis obvious that various modifications thereof will occur to personsskilled in the art.

In said drawings: Figure 1 is an elevational view of a fragment of a carside equipped with a door having door fixtures formed and attached tothe door as contemplated in accordance with the present invention. Fig.2 is a vertical sectional view taken on line 22 of Fig. 1. Fig. 3 is avertical sectional view taken on line 33 of Fig. 1. Figs. 4 and 5 arehorizontal sectional views taken, respectively, on lines 4-4 and 55 ofFig. 1. Fig. 6 is an edge view of the hanger showing the lugs 10extending laterally from the body of'the hanger.

The object of the invention is to provide a door formed of sheet metalof light weight, which is reinforced by means of corrugations extendingverticall and horizontally, and is especially inten ed for use in carconstruction, though the door is adapted to other purposes.

' One of the objects of the invention is to utilize the door fixtures asmeans for securing together the sheets forming the doors.

Another object is to provide fixtures of 1' such contour that lparts ofthe fixtures will rest within channe portions of the corrugations in oneface of the door in such manner that torsional disturbances of theconnected fixtures and door will be avoided.

Other objects of the invention are economy of manufacture andutilization, with but "sli ht chan'gesin details of formation, of stanard fixtures which are'well known in theart. I

" Primarily, the-'invention-consists-of par- Specification of LettersPatent. Patented Ma, 10 1914 Application filed July 8, 191a.

Serial No. 777,842.

of door fixtures intended to be used for supporting, locking and guidingthe door, which fixtures are so disposed with relation to thecorrugations that the contour of parts of the fixtures is utilized toprevent displacement, in addition to which the fixtures are secured tothe corrugated sheets of the door by means which connect such sheetstogether and reinforce the part of the door within the zone ofconnection of fixtures to the door. I

Referring specifically to the drawings, A indicates the door which, aswill be noted in the sectional views Figs. 2, 3, 4 and 5, is composed ofparallel sheets B and G, which sheets B and C are provided withcorrugations intersecting at right angles and com;

prising channel portions D and ribs E,which ribs outline the channels.The fixtures comprise door hangers, door lockin means and the handle forshifting the oor. These parts are secured to the outer face of the door,as is common in car construction.

Referring specifically to the hanger, it will be noted that said hangeris provided with a bracket 1, an upward extension 2, terminating in aninset portion 33, carrying a supporting wheel or roller 4 and with anintegral guide finger 5, and that the track portion for the hanger isprovided with an upper flange 6, a vertical web 7 a horizontal flange 8and a depending vertical flange 9, on the horizontal flange 8 of whichthe roller 4 travels and the flange 9 laps the upper edge of the door,while the finger 5 of the hanger is interposed between the door and theflange 9.

The bracket portion 1 of the hanger is provided with integral perforatedspaced lugs 10, which lugs are spaced vertically and horizontally, asshown in Fig. 6, so that said lugs will occupy and substantially fillthe channels D in the face of the door in which they rest, the remainingportions of the hanger lapping the door and extending upwardly above thesame as shown.

a It is evident that with a door suspended from above by means ofhangersof the type shown, there is a considerable degree of torsion onthe hanger, and when rivets alone are used as securing means to connectthe hanger to the door there is a probability of the rivets workingloose, which would re sult in some lost motion. Owing to the thin metalof which the door proper is composed, this tendency is materiallyincreased, hence it is desirable to protect the connection of the doorhanger to the door to avoid such torsional disturbance. This isaccomplished by the lugs of the hanger which rest within the channels D,substantially filling said channels, whereby the outstanding ribs E onthe outer face of the door will serve as side abutments for the lugs,and to better assist in preventing such torsional disturbance the lugsare spaced apart vertically, the grip of the lugs being assisted by suchvertical spacing and by the horizontal spacing shown, so that more thanone vertical channel D is occupied by the lugs. It is evident that thehorizontal and vertical spacing thus assists in holding the door hangerin position. The vertical spacing of the lugs is indicated because thedoor hangers are formed of cast metal, which can be better formed withlugs spaced apart both vertically and horizontally as shown, though itis evident that the vertical lugs may be connected by an intermediateweb, if desired, though where the bracket is made of malleable iron thelugs may be better annealed when they are formed separately asindicated.

The locking fixture is secured to the door in substantially the samemanner as the door hanger bracket, and said locking fixture comprisesthe plate 20, which is provided with the integral horizontally spacedlugs 21, which, like the lugs of the door hanger, are perforated. Theplate 20 has cooperating with it a supplemental locking plate 22, whichis connected by hooked engagement with the plate 20, a hooked end 23engaged with the perforation 20 of the plate 20, as shown in Fig. 4, andrivets 25 secure the lockingplate in position, the same rivets securingthe plate 20 to the door, thereby providing a recess between said platesfor the ring 25 of the hasp 26.

It is understood that the hasp extends beyond the edge of the door andis adapted to interlock with a suitable stud 30, the usual door sillbeing employed for that purpose.

The handle on the outer side of the door, by means of which the door isshifted, is of the conventional form, comprising the loop 31, which,like the door hanger bracket and the hasp plate, is provided withinwardly extending studs 32, which studs are perforated for the passageof the rivets 33, adapted to secure said handle in position.

As will be noted in the drawings, the studs 32 are arranged in pairs,one pair at each end of the door handle and the members of each pairbeing arranged vertically so as to occupy proper positions within thevertical channels in the outer face of the door.

A feature common to the door hanger, hasp plate and to the handle ismeans to prevent rupture of the thin metal plates forming the-door, thisfeature consisting of a bar or series of bars 35, resting within thehorizontal channels on the inner side of the door and extending farenough horizontally to receive the horizontally spaced rivets of thedoorhanger, one of the bars 35 being disposed at the middle portion ofthe hanger bracket and another of the bars being disposed near the lowerportion of the bracket, as-best shown in the sectional view Fig. 2-.

The hasp plate is likewise reinforced in its connection to the door bymeans of a bar 35 which, as shown in Fig. 4, has suflicient length toreceive through it the four rivets shown as connecting the hasp plate tothe door. Likewise the handle 31 is connected to the door, the rivets 33extending through horizontally disposed bars 35 It is to be noted thatthe bars 3-5, 35* and 35 are suitably perforated for the passage of thesecuring rivets, and said bars are of substantially the width verticallyof the horizontal channels on the inner face of the door, within whichsaid doors are positioned. Thus, it will be apparent that while the doorfixtures are connected with the doors by direct rivet connection throughthe thin metal plates comprising the doors, such metal plates arereinforced within the zone of connection by means of the reinforcingbars indicated and rupture of the sheet metal of the doors iseffectually prevented. Suitable back stops, as 87, may be employed andbottom guides, 38, are provided for the lower edge of the door, as iscommon in car doors.

We claim:

1. In a railway car door, vertically disposed corrugations on the outerface thereof, a door hanger extending above the upper edge of the doorand extending downwardly and lapping certain of said verticalcorrugations and interlocked with the door against torsional stresses bymeans of lugs projecting from the hanger inwardly within a channelformed by said corrugations and in juxtaposition to and betweenoutwardly extending ribs outlining said channels, and fixture securingmean projected through said from the fixture intween outwardly extendingribs outlining said channels, and fixture securing means projectedthrough said hollow lugs and through the door.
